Abstract

A surgery-assisting device includes a robot arm that includes plural movable bodies that are operably connected in order in a connecting direction, a surgical instrument connected to a distal end of the robot arm, and one or more actuators that generate a driving force that operates one or more of the movable bodies. The movable bodies include one or more distal-side movable bodies that is provided distally in the connection direction, and one or more proximal-side movable bodies that is provided proximally in the connection direction. An operation tolerance of the one or more distal-side movable bodies is higher than an operation tolerance of the one or more proximal-side movable bodies.
